Surfing around Google Maps I found some very interesting places. One that caught my attention was the Firefox crop circle.
From Wikipedia: Crop circle is a term used to describe geometrical formations of flattened crops — primarily wheat, barley, canola, rye, corn, linseed and soy — that sometimes appear on different locations around the world.

Still from Wikipedia: The phenomenon itself was observed in its current form after notable appearances in England in the late 1970s. Cereologists, or crop circle enthusiasts, soon offered various paranormal and naturalistic explanations for the phenomenon. In 1991, two men named Doug Bower and Dave Chorley revealed that they had been making crop circles in England since 1976 using planks, rope, hats, and wire as their only tools. Circlemakers.org, a UK-based arts collective founded by John Lundberg have been creating complex crop circles since the early 1990s.
Here is the location of this crop circle from Google Maps, and here’s more on the making of the Firefox Crop Circle. Shown below is the location of the crop circle from Microsoft Virtual Earth (crop circle not shown).
